php比较坑的地方就是实现同样的目的,可以使用超级多种手段。比如(file_get_contents和fopen以及现在提到的curl以及fsockopen当然还有socket)这对于一个经验少的程序员来说,确实比较难选。、

所以很多情况下,我们需要比较。搜索一下网上不负责任的资源,做一个预测。然后亲自比较权衡一下。

下面是摘抄的:

function curlRequest($url, $isPost = false, $param = array(), $cookie = null, $header = null, $referer = "", $timeout = 60) {        $ch = curl_init();        curl_setopt($ch, CURLOPT_URL, $url);        if (is_array($header) && !empty($header)) { //设置header            $set_head = array();            foreach ($header as $k => $v) {                $set_head[] = "$k:$v";            }            curl_setopt($ch, CURLOPT_HTTPHEADER, $set_head);        } else {            curl_setopt($ch, CURLOPT_HEADER, 0);        }        if ($isPost === true) {            curl_setopt($ch, CURLOPT_POST, $isPost);            curl_setopt($ch, CURLOPT_POSTFIELDS, $param);        }        if (!empty($cookie)) {            if (is_array($cookie)) {                $cookies = implode(';', $cookie);            } else {                $cookies = $cookie;            }            curl_setopt($ch, CURLOPT_COOKIE, $cookies);        }        if (!empty($referer)) {            curl_setopt($ch, CURLOPT_REFERER, $referer);        }        if( $timeout > 0 ) {            curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);        }        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);        $ret = curl_exec($ch);        if (curl_errno($ch)) {            $ret = '';        }        curl_close($ch);        return $ret;    }

一般的过程,我们不会用到那么复杂:

<?php    $startTime = microtime(true);    $url = "http://api.k780.com:88/?app=weather.today&weaid=1&appkey=10003&sign=b59bc3ef6191eb9f747dd4e83c99f2a4&format=xml";    for($i = 0 ; $i < 2; $i++){        $handle = curl_init($url);        //$defaultHeader = array('Accept-encoding: gzip, default');        curl_setopt($handle, CURLOPT_RETURNTRANSFER, 1);        //curl_setopt($handle, CURLOPT_HTTPHEADER, $defaultHeader);        curl_setopt($handle, CURLOPT_CONNECTTIMEOUT, 10);        curl_setopt($handle, CURLOPT_TIMEOUT, 10);        $xml = curl_exec($handle);        if($i % 10 == 0){            echo ".";        }        curl_close($handle);    }    $endTime = microtime(true);    $total = $endTime - $startTime;    echo $total;    echo curl_error($handle);?>

需要说明的是:curl在控制台是不能运行的,比如php xxx.php params_1,它需要服务器。
